SASH FASTENER.

" Application filed September as, 1921. Serial No. 503,770.

To all whom it may concern:

relatively movable parts fastened while open to a greater or less degree or in the closed position.

A further object of the invention is to provide a latch comprising members for application to the respective meeting rails and adapted to be entirely disconnected whendesired and maintained in positions preventing possibility of breakage of the window or accidental engagement with the sash part.

More specifically, the invention has in view the production of a fastener of the indicated type of simple construction and few parts that maybe adjusted with facility for the fastening-of the closed sashes, or partly open sashes.

Reference is to be had to the accompanying drawings forming a part or" this specifi cation, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a plan view of a'latch embodying my invention showing the same mounted for use, the view showing the parts in looking position;

Figure 2 is a vertical section on the line 2--2 Figure 1;

Figure 3 is a vertical section at right angles to Figure 2 as indicated by the line 8--3, Figure 1;

Figure 4 is a side elevation of the latch adjusted to lock the sashes when opened to a limited extent, the view showing the sash parts in transverse vertical section;

Figure 5 is a side elevation of the latch and a transverse vertical section of the adjacent sash parts, the view showing the latch parts disconnected and so disposed as to constrain the parts in position permitting free movement of the sashes.

In carrying out my invention, in practice, in accordance with the illustrated example,

, the latch elements carried by the outer sash include a base plate 10. secured to the meeting rail A of said outer sash by screws 11 or the like and having upstanding spaced members 12 separated to present a vertical slot 13 therebetween. An elongated jswingable latching member 14 is pivotally mounted on the baselO to swing tofan upright position parallel with the outersash or' to a transverse position overlying the meeting rail B of the lower sash. Said locking element14 has the end l5 thereof disposed between vertical flanges 17 on base .10 to which said flange is pivoted by the transversepi ns 16. The latch element 14 has a longitudinal slo/lS therein, the slot being closed'at 'both' en s.

A base plate 19 is provided adapted to be secured by screws 20 or the like to the meet ing railB of the inner sash and has a raised central portion" 21in. the top of which is a longitudinal slot 22 registering with the slot 18 when the'element 14 is lowered onto said raised portion. A latching element 23 has a transverse .pin 24 or otherwise is formed to present trunnions which travel in the raised portion 21' beneath the top thereof, the slot 22 permitting the movement of said latch ,ele1nent28 in a plane transverse to the plane of the sash. Said element 23 is adapted to pass through the slots 22 and 18, the upper end ofsaid element-23 being in the form of a reduced. and thr'eaded shank 25 having a milled nut 26 or equivalent nut. The inner end of the slot 22 is open so that the element 23 may be completely detached from the raised portion 21 so as to swing with the plate14 away from the plane of the-inner sash B to a position within the plane of the outer sash A.

With the above described construction when it is desired to fasten the sashes in closed position as in Figure 2 the element 23 is slid to the outer end of the slot 18 and the plate 14 with said element 28 and nut 26 is lowered onto the raised portion 21. The

'trunnions'prcsented by the cross pin 24 are passedbeneath the slot 22, the element 23 sliding in said slot. Thus, the trunnions will be disposed beneath the top of the raised portion 21 at each side of the slot 22, the element 23 lying in said slot 22 and its threaded shank 25 extending through the slot 18. In this position of the parts the nut 26 will be above'the element 14 so that'the tightening of said nut will firmly bind said element 1-l onto the raised pOrtion 21 to prevent movement of the sashes. By loosening the nut 26 the element 23 is permitted sliding movement in the slot 22 and by moving the element 23 so that the trunnion pin 2 1 will lie at the end of the raised portion 21, the

latch element 14- is permitted a limited rocking movement on its pivot pin 16 to permit portion 21, the nut 26 is turned back sufficiently for the element 23 to he slid in the slot 18 to the free end of the element 1 1 and entirely disengaged from the raised portion 21. The element 14 may then be swung into the plane of the outer sash A and the element 23 and nut 26 dropped to the upstanding members 12 on the base 10 in which position of the parts the tightening of the nuts 26 will serve to tightly bind the element 1%: to the members 12 to prevent accidental movement of said element out of the plane of the outer sash to thereby insure clearance for the relative movement of the sashes.

I would state in' conclusion that while the illustrated example constitutes a practi 1 swing to a position in the plane of the outer sash. or transversely to said plane to. overlie an inner meeting rail, an element adapted to be secured to the meeting rail of the inner sash, and a clamp slidable longitudinally of said first element and having means to rockably and slidably engage the second element.

2. A sash fastener including a latch element, means to pivotally mount said element on the meeting rail of an outer sash to swing to or from a position overlying the inner meeting rail, an element adapted to be secured to the inner meeting rail and clamp means slidable on the first element to different positions and adapted to rockably engage the second element and to slide to different positions on the second element, said clamp means being adapted in its various positions to bind the first and second elements against relative movement.

A latch comprising two slotted clcments adapted to be secured respectively to parts to be held against relative movement, and clamp means carried by one of said slotted elements to be moved lengthwise thereof and adapted to slidably and rockably engage the other element or to hold said elements immovable.

4;. A. sash fastener including an element adapted to be secured to the meeting rail of an inner sash and pivoted to swing to a position within the vertical plane of said meeting rail or transversely thereto, an element adapted to be secured to an inner meet- .ing rail, clamp means slidable on the first element and adapted to engage the second element audbind the latter to the first ele ment, and means engageable by the clamp means to secure the first element in its firstmentioncd position.

5. IL sash fastener comprising a slotted elongated element, means to pivotally mount said element on the meeting rail of an outer sash to swing within the plane of said rail, or to a transverse position across an inner meeting rail, an element adapted to be secured to the inner meeting rail and having a slot open at an end thereof, and a clamp on the first element and adapted to move into or out of the slot in the second element through the open end thereof, saidclamp having trunnions to roclcably engage said second element.

I 6. A sash fastener including a base adapted to be secured to the meeting rail of an outer sash, a latch element pivoted to said base to swing to an upright position or to a position overlying an inner meeting rail,

said base having spaced upstanding members, a clamp slidable on said element to a position on said members for clamping said element to said members, and a second ele ment adapted to be slidably and rockably engaged by said clamp to bind both of said elements against movement.
